It would be great to be able to preview pano videos in real time (or as close to as you can get) in the Oculus or Vive headsets. Things look very different in the headset compared to spread out flat on a screen, and having to render the movie, fire up the Oculus app, load the video takes time. Direct rendering to the Oculus (even at reduced resolution/frame rates) would make that preview process so much faster.
